Unlike the driver-only memory seat in the Ascent Limited/Touring, the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.
The GLB’s standard easy entry and exit feature glides the driver’s seat back, making it easier for the driver to get in and out. The Ascent doesn’t offer an easy entry system.
The GLB offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Ascent doesn’t offer a heads-up display.
The power windows standard on both the GLB and the Ascent have locks to prevent small children from operating them. When the lock on the GLB is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Ascent prevents the driver from operating the other windows just as it does the other passengers.
The GLB’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Ascent’s rear power window switches have to be held the entire time to open or close them fully.
If the windows are left open on the GLB the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Ascent can only operate the windows from inside the vehicle, with the ignition on.
The GLB’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Access and Start is an extra cost option on the Ascent and doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door. Keyless Access and Start is not available on the Ascent Base.
The GLB’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Ascent’s standard manually variable intermittent wipers have to be constantly adjusted.
Heated windshield washer nozzles are optional on the GLB to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Ascent doesn’t offer heated windshield washer nozzles.
The GLB’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the Ascent Premium/Onyx/Limited/Touring.
When the GLB is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Ascent’s mirror doesn’t automatically adjust for backing.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLB has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Ascent.
The GLB’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The Ascent doesn’t offer an automated parking system.
